    “…On the other hand we infer larger limits for non-flat cosmologies. From the full CMB likelihood analysis we also estimate the values of the shift parameter R and the mu ltipole l_a of the acoustic horizon at decoupling for several cosmologies to test their dependence on model assumptions. …”

    “…Horava-Lifshitz gravity, a recent proposal for a UV-complete renormalizable gravity theory, may lead to a bouncing cosmology. In this note we argue that Horava-LIfshitz cosmology may yield a concrete realization of the matter bounce scenario, and thus give rise to an alternative to inflation for producing a scale-invariant spectrum of cosmological perturbations. …”
